HENRY M. MYERS, OF BEAVER FALLS, PENNSYLVANIA.

MACHINE FOR FORMING SHOVEL-BLANKS.

SPECIFICATICN forming part of Letters Patent No. 340,95 dated April 27, 1886.

Application filed March 27, 1885v To aZZ whom it may concern;

Be it known that I, HENRY M. MYERS, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Manufacturing Blanks or Bars for Blanks for Shovels, Spades, and Scoops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in machines for manufacturing blanks or bars for blanks for shovels, spades, and scoops; and it consists in the construction of the machine hereinafter described,and particularly pointed out in the claims.

To enable others skilled in the art with which my invention is most nearly connected to make and use it, I will proceed to describe its construction and operation.

In the accompanying drawings, which form part of this specification, Figure l is a'perspective View of my improvement in machines for making blanks or bars for blanks to be used in the manufacture of shovels, spades, and scoops. Fig. 2 is a vertical section ofthe same at line 00 0c of Fig. 3. Fig. 3 is a hori zontal section. Fig. 4. is a top view or plan of a bar for forming blanks.

Reference being had to the accompanying drawings, A represents the base of the machine; B, the bed-plate; G, a recess made in said bed-plate for the reception of a plunger, D, which is operated by a cam, E, on the shaft F. In the bed-plate B is also a recess, G, for the reception of a bar of iron, marked P. (Shown in Fig.1.)

From the upper side of the bed plate B projects a frame, H, in which is journaled a shaft, I, upon which are arranged cams J K. The cam J is for operating a clamping-plate, M, and cam K for operating the cutter L. Q B are driving-pulleys.

In the recess G of the bed-plate B is a recess, S, which is for the purpose of forming the arm N of the blank 0. The clamping-plate M and the cutter L move in suitable guides in the frame H, and are operated by the cams J K, through the medium of pitmen T U. The

bed plate B is provided with an opening, V, for receiving the cuttingedge of the cutter L.

It will be observed that from the construetion shown and described the plate B forms a die having a fixed bottom and one fixed side, and that the clamping-plate M constitutes a movable top to the die and holds the bar in position, preventing its being thickened by the action of the plunger D forcing the metal into the recess S to form the arm N on the bar.

From the foregoing description, and by reference to the accompanying drawings, the skillful mechanic will readily understand the construction of the machine.

The machine being put in operation, aheated bar of the form shown at I, Fig. 1, either from the rolls or a heating-furnace, is inserted in the recess G. The clamping-plate M then descends and is held in a fixed position a sufficient length of time for the plungerD to move in the recess 0 and under said clamping-plate and force a portion of the metal of the heated bar into the recess S in the bed-plate B, for the purpose of forming the arm N of the blank 0, at which point the plunger D is drawn back and the clamping-plate M is elevated, allowing the operator to raise the bar from the recess S and move it forward, which being done the cutter L descends and severs the blank 0 from the bar, and thus the operation is continued until the bar is worked up into blanks.

The machine may be provided with means for automatically feeding the bar of metal or with suitable gages to enable the operator to move the bar the proper distance to feed the die at each operation of the machine.

By detaching the cutter L the machine may be used for the purpose of forming a bar for the manufacture of blanks such as shown in Fig. 4., which bar is claimed in another application herewith filed, Serial No. 160, 24-1, as a new article of manufacture.

It will be observed that the arm S of the die, substantially as described.

the blank is claimed in another application filed herewith, Serial No. 160,247.

Having thus fully described my invention, What I claim is- 1. In a machine for forming blanks or bars for blanks for the manufacture of shovels, a die having a fixed bottom and a fixed side, a movable top for the die, and a plunger, substantially as described.

2. I11 a machine for forming blanks or bars for blanks for the manufacture of shovels, a die having afixed bottom and a fixed side provided with a recess, a laterally-movable plunger, and a Vertically-movable top for the v 3. In a machine for forming blanks or bars for blanks for the manufacture of shovels, a

bed-plate or die provided with a fixed bottom, arecess in its side, and an opening for receiving the cutter, in combination with a laterallymovable plunger, a movable top for the die, and a verticallymovable cutter adapted to project into theopening in the bed-plate, substantially as described.

4. In a machine for forming blanks or bars for blanks for the manufacture of shovels, a bed-plate or die having a recess formed in its side, and alaterally-movable plunger, in combination with a frame supported by the bed plate and a vertically reciprocating plate guided by the frame and adapted to form a top or cover for the die, substantially as shown.

5. In a machine for forming blanks or bars for blanks for the manufacture of shovels, a bed-plate or die provided with recesses, as G, G, and S, and the opening V, in combination with a laterally-movable plunger, a movable top or cover for the die, and a vertically-movable cutter, substantially as described.
